BACKGROUND

At least some embodiments disclosed herein relate to data storage, and more particularly, to advertisement forwarding storage and retrieval network.

The volume of data that must be stored by individuals, organizations, businesses and government is growing every year. In addition to just keeping up with demand, organizations face other storage challenges. With the move to on-line, real-time business and government, critical data must be protected from loss or inaccessibility due to software or hardware failure. Today, many storage products do not provide complete failure protection and expose users to the risk of data loss or unavailability. For example, many storage solutions on the market today offer protection against some failure modes, such as processor failure, but not against others, such as disk drive failure. Many organizations are exposed to the risk of data loss or data unavailability due to component failure in their data storage system.

The data storage market is typically divided into two major segments, i.e., Direct Attached Storage (DAS) and Network Storage. DAS includes disks connected directly to a server.

Network Storage includes disks that are attached to a network rather than a specific server and can then be accessed and shared by other devices and applications on that network. Network Storage is typically divided into two segments, i.e., Storage Area Networks (SANs) and Network Attached Storage (NAS).

A SAN is a high-speed special-purpose network (or subnetwork) that interconnects different kinds of data storage devices with associated data servers on behalf of a larger network of users. Typically, a SAN is part of the overall network of computing resources for an enterprise. A storage area network is usually clustered in close proximity to other computing resources but may also extend to remote locations for backup and archival storage, using wide area (WAN) network carrier technologies.

NAS is hard disk storage that is set up with its own network address rather than being attached to the local computer that is serving applications to a network's workstation users. By removing storage access and its management from the local server, both application programming and files can be served faster because they are not competing for the same processor resources. The NAS is attached to a local area network (typically, an Ethernet network) and assigned an IP address. File requests are mapped by the main server to the NAS file server.

All of the above share one common feature that can be an Achilles tendon in more ways than one, i.e., data is stored on a physical medium, such as a disk drive, CD drive, and so forth.

DETAILED DESCRIPTION

Unlike peer to peer networks, which use data forwarding in a transient fashion so that data is eventually stored on a physical medium such as a disk drive, the present invention is a continuous data forwarding system, i.e., data is stored by continually forwarding it from one node memory to another node memory.

As shown in FIG. 1, an exemplary network 10 includes a user system 12 and a number of network systems 14, 16, 18, 20, 22. Each of the network systems 14, 16, 18, 20, 22 can be considered to be a node in the network 10 and one such network system may be designated as a central server, such as network system 14, which may assume a control position in network 10. Each of the nodes 14, 16, 18, 20, 22 may be established as a privately controlled network of peers under direct control of the central server 14. Peered nodes may also be a mix of private and public nodes, and thus not under the direct physical control of the central server 14. The network 10 may also be wholly public where the central server 14 (or servers) has no direct ownership or direct physical control of any of the peered nodes.

As shown in FIG. 2, the user system 12 can include a processor 30, memory 32 and input/output (I/O) device 34. Memory 32 can include an operating system (OS) 36, such as Linux, Apple® OS or Windows®, one or more application processes 38, and a storage process 100, explained in detail below. Application processes 38 can include user productivity software, such as OpenOffice or Microsoft® Office. The I/O device 34 can include a graphical user interface (GUI) 40 for display to a user 42.

As shown in FIG. 3, each of the network systems, such as network system 14, can include a processor 50 and memory 52. Memory 52 can include an OS 54, such as Linux, Apple® OS or Windows®, and a data forwarding process 200, explained in detail below.

In traditional systems, application processes 38 need to store and retrieve data. In these traditional systems, data is stored on local or remote physical devices. And in some systems, this data can be segmented into different pieces or packets and stored locally or remotely on physical mediums of storage. Use of fixed physical data storage devices add cost, maintenance, management and generate a fixed physical record of the data, whether or not that is the desire of the user 42.

The present invention does not use fixed physical data storage to store data. When a request to store data is received by the central server 14 from storage process 100, data is directed to a node in the network 10 where it is then continuously forwarded from node memory to node memory in the network 10 by the data forwarding process 200 in each of the network nodes without storing on any physical storage medium such as a disk drive. The forwarded data resides only for a very brief period of time in the memory of any one node in the network 10. Data is not stored on any physical storage medium in any network node.

In a like manner, when a request to retrieve data is received by the central server 14 from storage process 100, the requested data, which is being forwarded from node memory to node memory in the network 10, is retrieved.

Data forwarded in this manner can be segmented and segments forwarded as described above. Sill, the segmented data is not stored on any physical storage medium in any network node, but merely forwarded from the memory of one node to the memory of another node.

As shown in FIG. 4, storage process 100 includes sending (102) a request to a central server 14 to store or retrieve data. If the request is a retrieve data request, storage process 100 receives the requested data from the central server 14 or node in the network.

If the request to the central server 14 is a store data request, storage process 100 receives (104) an address of a node from the central server 14 and forwards (106) the data to the node memory represented by the received address. Determining an address of a node available to receive the data can be based on one or more factors, such as network traffic analysis, available memory, combinations of factors, and so forth. A time stamp can be applied to the data in the computer memory of the specific node.

As shown in FIG. 5, data forwarding process 200 includes receiving (202) a request to store or retrieve data. If the received request is a request to store data, data forwarding process 200 determines (204) an address of a node available to receive the data in memory. This determination (204) can include pinging the network and determining which of the nodes in a network is available, or determining which node in the network has the least traffic, or determining which node in the network has the largest available memory, or any combination of these or other factors.

Process 200 sends (206) a message to the user system with the address of a specific node for the requester to forward the data.

Process 200 detects (208) the presence of data in node memory. Process 200 forwards (210) the data in memory to another node in the network of nodes and continues to repeat detecting (208) and forwarding (210) of the data from node memory to node memory. When data arrives in any node memory, process 200 affixes (212) a time stamp to the data.

Forwarding (210) can include pinging the node in the network to determine which of the nodes in the network is available, or determining which node in the network has the least traffic, or determining which node in the network has the largest available memory, or any combination of these or other factors.

In one specific example, at the point of entry to a node, data undergoes an encrypted “handshake” with the node or central server 14 or user. This can be a public or private encryption system, such as the Cashmere system, which can use public-private keys. Cashmere decouples the encrypted forwarding path and message payload, which improves the performance as the source only needs to perform a single public key encryption on each message that uses the destination's unique public key. This has the benefit that only the true destination node will be able to decrypt the message payload and not every node in the corresponding relay group. Cashmere provides the capability that the destination can send anonymous reply messages without knowing the source's identity. This is done in a similar way, where the source creates a reply path and encrypts it in a similar manner as the forwarding path.

In another example, other routing schemes are utilized.

If the received request is a request to retrieve data being continuously forwarded from node memory to node memory, data forwarding process 200 matches (214) at the central server 14 using a hash mark or other unique code that can be “sniffed” by the node upon the data entering the node via the encryption handshake. This can occur by pinging the nodes in the network. Process 200 sends (216) the message to return the data to the user directly to the node or node state where the central server 14 believes the data will likely appear. The more the central server 14 can narrow the node state that it pings to, then the more efficient the retrieval will become and the less burdened by unnecessary messaging traffic to nodes that are not necessary for a transaction between the central server 14 and the node capable of forwarding the data.

Once the correct node receives the message to forward the data in node memory to the requester, process 200 forwards (218) in node memory the data to the requester and forwards (220) a confirmation message that the data has been sent to the user. This routing message may be sent directly to the central server 14 or may be passed to the central server 14 or servers via other node(s) or supernode(s) in the network 10. Upon the user receiving the requested data the user's application functions to automatically ping the central server 14 that the data requested has been received. Thus the network 10 creates data storage without caching, downloading and/or storing the data on any physical storage medium. Data storage and management is accomplished via a continuous routing of the data from node memory to node memory, the forwarded data only downloaded when the user requests the data to be returned to the user from the network 10.

New nodes and node states may be added and/or deleted from the network 10 based upon performance. Users may have access to all nodes or may be segmented to certain nodes or “node states” by the central server(s) or via the specific architecture of the private, public or private-public network.

Individual nodes, nodes states and supernodes may also be extranet peers, wireless network peers, satellite peered nodes, Wi-Fi peered nodes, broadband networks, and so forth, in public or private networks. Peered nodes or users may be used as routing participants in the network 10 from any valid peer point with the same security systems employed, as well as custom solutions suitable for the rigors of specific deployments, such as wireless encryption schemes for wireless peers, and so forth.

In process 200, rather than have data cached or held in remote servers, hard drives or other fixed storage medium, the data are passed, routed, forwarded from node memory to node memory. The data are never downloaded until the authorized user calls for the data. A user on the system may authorize more than one user to have access to the data.

A primary goal in process 200 is to generate a data forwarding storage and management system where the data is never fixed in physical storage, but in fact, is continually being routed/forwarded from node memory to node memory in the network. The path of the nodes to which data is forwarded may also be altered by the central server 14 to adjust for system capacities and to eliminate redundant paths of data that may weaken the security of the network due to the increased probability of data path without this feature.

This data forwarding storage and management system in which the data is never fixed in physical storage, but in fact, is continually being routed/forwarded from node memory to node memory in the network, can be used as a backend system(s) in many applications that currently used fixed medium storage. In one example, this data forwarding storage and management system where the data is continually being routed/forwarded from node memory to node memory in the network is used as an advertisement forwarding and retrieval system. Advertisement is deployed into the data forwarding storage and management system from a master server or control station and recalled on demand or in response to a stimulus or activity. Here, we consider advertisement as a broad term that can include any content, including, but limited to, text, audio, visual or any combination thereof. Advertisement can be deployed into the data forwarding storage network and recalled/retrieved when needed, e.g., directed to an IP address of a specific user system, directed to paid and/or unpaid subscribers of applications within the data forwarding storage network, and/or directed to users outside of the data forwarding storage network. Advertisement being continuously forwarded in the data forwarding storage network can be sent to all users or specifically targeted according to one or more user characteristics, user profiles, usage patterns, history and/or past or present viewed page content. The advertisement being continuously forwarded in the data forwarding storage network can be displayed to a current user within an application or web browser or delivered to a wired or wireless radio, television and/or television network. Advertisements can be retrieved in response to a stimulus or activity, such as the user's profile, traffic patterns of one or more users, application profiles, and so forth. Advertisements can be stored and delivered in any media form and either pre-configured by specific file type and size for a specific end user or site delivery requirements/formats, or delivered and formatted by virtue of the end user or middleware software compatibility systems.

In one example, selected advertisement can be delivered to a user through a web browser. More particularly, a plug-in and/or helper application can be associated with a user's web browser. In general, a plug-in is a computer program that interacts with a host application (a web browser or an email client, for example) to provide a certain, usually very specific, function “on demand.” As a user navigates to a particular web page, the plug-in can parse displayed text. The plug-in can then request specific advertisement being continuously forwarded in the data forwarding storage network that matches the parsed text to the web browser of the user for display in a section of the display screen or as a pop-up.

In another example, a user requesting retrieval of a data file being continuously forwarded in the data forwarding storage network may be presented with specific advertisement being continuously forwarded in the data forwarding storage network that matches the user's profile. The user's profile may include various personal and/or demographic data that aids in directing appropriate advertisement to the user. The advertisement may then be displayed as a banner or in a shared window or in a separate window.

In each of the examples above, the network includes a group of interconnected computer system nodes each adapted to receive data and advertisement and continuously forward the data and advertisement from computer memory to computer memory, independent of each other, without storing on any physical storage device, in response to a request to store the data from a requesting system and retrieve data being continuously forwarded from computer memory to computer memory in response to a request to retrieve the data from the requesting system. Each node in the network is adapted to detect the presence of a data and advertisement in its memory and forward the data and advertisement to a computer memory of another node in the interconnected computer systems nodes according to a node's availability. The node's availability can be determined according to its volume of network traffic. Each node can encrypt the data.

A central node can be adapted to match the data retrieval request at a central server using a hash mark representing the data or advertisement entering a node, send a message to a node that is predicted to have the data or advertisement in memory, the message instructing the node to forward the data and/or advertisement in memory to the requester, and send a confirmation message to the central server that the data or advertisement in memory has been forwarded to the requester.

As shown in FIG. 6, a process 300 includes directing (302) advertisement to a computer memory. The advertisement can include any content, including, but limited to, text, audio, visual or any combination thereof The advertisement can include multiple configurations in order to satisfy different systems delivery specifications. Advertisements can be stored and delivered in any media form and either pre-configured by specific file type and size for a specific end user or site delivery requirements/formats, or delivered and formatted by virtue of the end user or middleware software compatibility systems.

Process 300 directs (304) data to a computer memory.

Process 300 continuously forwards (306) each of the unique data, independent of each other, from one computer memory to another computer memory in the network of interconnected computer system nodes without storing on any physical storage device in the network.

Process 300 continuously forwards (308) each of the unique advertisements, independent of each other, from one computer memory to another computer memory in the network of interconnected computer system nodes without storing on any physical storage device in the network.

Process 300 retrieves (310) one of the advertisements in response to an activity.
